Coronavirus vaccine may be ready for public November - China

AstraZeneca COVID-19 vaccine trial in US on hold until at least midweek-sources

Global trials of the vaccine had also been paused following the United Kingdom suspension.

"I joined the experimental group and had a coronavirus shot in April".

Worrisome adverse events haven't appeared so far, but fatigue has been the most common side effect noticed during the trials so far, as per the company presentation.

'[Researchers] would notify us if they had any safety concerns and have not done that to date, ' Dr Kathrin Jansen, Pfizer's head of vaccine research, said on the call.

In a statement on Monday, researchers at Imperial College London and Oxford University said a trial involving 30 people would test vaccines developed by both institutions when participants inhale the droplets in their mouths, which would directly target their respiratory systems.

Company CEO Albert Bourla has said it is "likely" the USA will get a coronavirus vaccine treatment to the public before the end of the year.

This means the FDA is only requiring data on 6,000 volunteers - 3,000 vaccinated and 3,000 given a placebo, the executives said.

Pfizer added it is continuously scrutinizing the safety and tolerability of the vaccine in its study.


'What we are doing in terms of releasing data is very unusual, ' CEO Albert Bourla said, according to Bloomberg News.

United States: AstraZeneca's COVID-19 vaccine trial remains on hold in the USA pending an investigation into the serious side effect in Britain even as other trials of the vaccine resume, sources told Reuters.

The British-Swedish pharmaceutical company's clinical trial was suspended last week after one volunteer was hospitalised and reportedly diagnosed with transverse myelitis, which causes inflammation in the spinal cord and is associated with viral infections.

Oxford University, AstraZeneca's partner on the vaccine, has already resumed its trial in Britain.

"These surfaces are specialised and produce a different immune response to the rest of the body, so it is critical we explore whether targeting the airways directly can provide an effective response compared to a vaccine injected into muscle".

Results showed the levels of neutralizing antibodies were between 1.8 and 2.8 times greater than those seen in recovered patients.

Sputnik V is the world's first coronavirus vaccine and was announced by President Vladimir Putin on August 11.
